Like Shaw, I used to be a kitchen gadget person. Even when I didn't buy them, I'd lust after them.
For me, it's less about the cheap, and more about the space. I'll pay $$ for a sturdy gadget that saves time and work... that I'll actually use.
Other than the toaster, coffeemaker and grinder, I have:
Hand mixer
Breadmaker (which is only used for mixing and rising - I do the baking in the oven)
Basic food processor - has two blades, and a glass base which can be run through the dishwasher. With both blades in, it does a good job with smoothies, shakes and ice. ($30 at Tuesday Morning)
I have a decent set of knives, and use the pastry knife and mortar/pestle my gran gave me all the time. It's faster to chop most things by hand than to get out the food processor, though I do use it when making a curry paste from scratch, guacamole, or something like that.
We got one of the s'mores cookers for christmas a few years ago - I don't think we ever opened ours, either.
